Solar power is getting increasing popularity as a dependable source for street lighting all over the world. Some of the benefits associated with solar street lights include reduced dependence on conventional energy, conservation of energy and less reliance on the national grid. In countries experiencing abundance of sunlight, solar lights are the best option to illuminate the streets, garden, parks and other public spaces.

Solar-powered lights are a perfect eco-friendly green lighting solution

Nowadays, solar street lights are powered by PV panels, in-built battery, LED lights and smart sensors, all integrated into a single compact unit. Solar LED street lights have emerged as a cost-effective and environment-friendly to light up roads and public spaces. LED lights are widely acknowledged for energy conservation, are long-lasting and good-looking, and are maintenance-free. These characteristics make LED-based solar street lights well-suited for commercial as well as domestic lighting applications.

Key Features

A modern solar street light has embedded solar panel, inbuilt lithium-ion batteries, battery management system, night and motion sensors as well as automatic controls. The fully automatic device comes with LEDs, inbuilt and replaceable Lithium-ion battery and passive infrared (PIR) sensors. A typical solar street light is weather-proof and water-resistant, has low insect attraction rate and low glare and has a longer life.

The embedded solar panel converts solar power into electrical energy which is stored in the inbuilt battery, and used for dusk-to-dawn lighting operations. The main innovation of modern solar street lights is the battery management system which is facilitated by the presence of night and motion sensors.

During the first 5 hours of night, the system works at average lumens brightness. Subsequently, the intensity of the light reduces till dawn or until PIR sensor is activated by human movement. When people are within a certain radius away from the light, it automatically turns to its full brightness. This smart feature makes solar street lights device a perfect combination of renewable energy and energy efficiency.

Solar powered lights by Deelat Industrial has been tried and successfully tested in a wide variety of domestic and commercial applications. The device is well-suited for lighting up streets, courtyards, gardens, parks, compounds, boundary walls, car parks etc. in an eco-friendly and cost-effective manner.

Unending Benefits

Due to off-grid nature of solar street lights, solar street lights incur minimal operational costs. Such lights are wireless in nature and are independent of the utility company. Compared to conventional street lights, solar street lights require almost zero maintenance. Due to the absence of external wires, these lights do not pose any threat of accidents like electrocution, strangulation and overheating. Infact, solar lights illuminate the streets throughout the night irrespective of power cuts and grid failures.

Solar street lights are a delight for environmentalists around the world as it can provide significant lowering of carbon footprint of individuals, homes and businesses. In other words, solar-powered lights are a perfect green lighting solution. In terms of cost, solar street lights are a better investment than conventional street lights if the capital as well as O&M costs are considered.

The Bright Future of Solar Lighting

Solar power is an appealing source of energy, considering that it is widely available and sustainable. However, only two percent of the world’s electricity is derived from solar as of 2018. In the past, the production of solar energy has been costly and fairly ineffective.

Good thing, new technological advancements over the past years have propelled this growing reliance on solar by lowering costs. Technological innovations also aim to expand the use of solar by further decreasing costs and improving the efficiency of solar panels.

The Importance of Solar Lights

Although there are many uses for solar power, solar lighting is one of the most prominent. Large electrical products need high energy levels to operate them. This means that it needs large solar panels to collect appropriate energy from the sun.

On the other hand, solar street lighting do not require large sources of energy and can thus be operated off much smaller panels. They provide a higher level of functionality and flexibility since the solar panels can be integrated into the lighting system.

The magnificence of solar lighting is that you can use it often and virtually any time without any cost except for the initial purchase. Direct sunlight is not even required to charge the batteries.  With advanced technology, new models of solar lights can charge even on a cloudy day.

Solar lights are well designed for outdoor usage, removing the need for risky electrical wiring. Excellent placement means maximum charging and the light turns on as the sun sets. While more extensive circuitry is required, solar lighting can also be used for interior lighting.

The Future of Solar Lighting

It is always difficult to predict the future. But by observing current trends in energy usage, solar energy industry, and prospective scientific research, we can catch a peek of what solar lighting could mean for the future:

Materials

Most likely, the materials that go into solar panels will change. Cell phone manufacturers, smartphones, electric vehicles, and cordless power tools all rely on the same rare earth component array that solar panel makers do.

Worldwide stocks of these resources continue to decline. Due to this, scientists have warned companies producing high-tech gadgets to find alternatives (such as iron pyrite or zinc). Experts advise manufacturers to develop their metal recycling and recovery systems.

Cost

New designs will be developed to absorb more light and convert light energy more efficiently into electricity. Upcoming solar light models will also be less costly to build than existing designs to outperform current solar cells.

Electricity producers and consumers are more likely to embrace solar power if it is as costly or more affordable than others. Any changes to current designs of solar cells should reduce overall costs to be widely accepted.

Silicon solar cells are likely to persist to fall in price and be manufactured in large numbers in the near future. Additionally, research will continue on alternative models for solar cells that are more powerful and less costly.

With the bulk production of solar cells and emerging technologies, these developments will continue to be made possible.

Solar Power Usage

As the fight against climate change is escalating, so will the demand for renewable energy sources. Solar power will play a significant role in combating global climate change.

Solar could also spread to developing countries in the form of microgrids. Microgrids are distributed installations of electricity generation that provide energy to a limited area like a town, community, or a neighborhood.

Solar microgrids are an effective way to electrify remote communities in Africa or Southeast Asia. It is most effective for developing nations where it is too costly for electricity companies to connect far-flung towns to the power network.

Transparent Solar Cells

This advanced form of solar cells is adequately transparent for many new applications. Researchers developed a model that includes organic salts that absorb enough UV and infrared light to turn solar radiation into energy

Picture this sort of solar cell on the screen of a smartphone or a car’s windshield. Ultimately, transparent solar cells are more appealing than the conventional dark-colored panels and have a wider range of uses.

Final Thoughts

The use of solar lighting dates back to a thousand years ago when man first discovered fire. However, it is also very much the present and will be a significant part of the future. Solar lighting is here to stay until the sun shines its last beam, and as technology advances, the developments can grow over and over again.
